Severe hypokalemia in the absence of other electrolyte abnormalities, the result of diarrhea, caused striking electrocardiographic changes, generalized weakness, flaccid paralysis of the lower extremities, and biochemical evidence of mild…
Although acute myocardial infarction is the most clinically significant cause of ST-segment elevation, other serious clinical conditions have been reported with this electrocardiographic abnormality. We report a patient with pneumomediastinum…
This article is in Memoriam of Dr. Bernard D. Kosowsky who passed away in November 2015 at the age of 78 while riding his bicycle to work. Dr. Kosowsky was…
This year marks the bicentennial of the invention of the stethoscope by René Théophile Hyacinthe Laennec in 1816, working at the Necker Hospital in Paris. Mediate auscultation was a logical…
Adoption of appropriate use criteria has not had a major impact on the frequency of “rarely appropriate” tests, with the rarely appropriate tests rate remaining at ∼20% in most institutions….
Complementing the physical examination with a point-of-care ultrasound study (POCUS) can improve patient triage. We aimed to study the impact of POCUS on the diagnosis and management of outpatients and…
Diastolic waves are commonly seen in the left ventricular outflow tract on echocardiography. This work focuses on the E-reversal wave (Er) that occurs early in diastole, shortly after the mitral…
A wide variety of multivariable risk models have been developed to predict mortality in the setting of cardiac surgery; however, the relative utility of these models is unknown. This study…
Follow-up data and correlation of arrhythmias, electrocardiogram (ECG) changes, and cardiac function in anomalous left coronary artery from the pulmonary trunk or artery have not been previously studied. This is…
Computed tomography pulmonary angiogram (CTPA) provides a volumetric assessment of clot burden in acute pulmonary embolism (PE). However, it is unclear if clot burden is associated with right-sided heart strain…
